According to Antiquiet, early in the set Love made an incoherent speech about The Smashing Pumpkins — claiming that Billy Corgan wrote all the songs on ‘Siamese Dream’ and ‘Mellon Collie and the Infinite Sadness’ about her. She also alleged that the lyrics, “The killer in me is the killer in you” from ‘Disarm’ were cribbed directly from a letter she wrote to Corgan.

'Heart-Shaped Box' is clearly about how Kurt wanted out of their relationship. The 'umbilical-noose' line is obviously referencing how he felt trapped by her once she got pregnant and he had to 'crawl back'. That song doesn't paint her in a very good light at all so I don't know why she'd brag about it to Lana Del Ray, lol.
